In this process, air enters a duct (which is assumed to be perfectly insulated in order
to satisfy the condition for an adiabatic process) at dry-bulb
temperature T1 and moisture content g1 and leaves the duct
at dry-bulb temperature T2 and moisture content g2. The latent heat
gained by the air is
equal to the sensible heat loss by the air. i.e.
here hfg is the latent heat of water. If the water tank is infinitely long, the air at the outlet will
be 100% saturated. The temperature at this
condition is known as adiabatic saturation temperature. Related topics:
